Hi Ilija,
my focus on the recent contribution was the actual HAL layer, not the /dev
contributions. I wanted to make sure, that we finally start to get the HAL
integrates, I was assuming, that it will be easier to swap some of the drivers.
But here some additional comments on the drivers:

- FLEXCAN - Karl is now owning this driver (he was the one that sent you the
package) and he is currently on vacation. Once he is back, he can look at your
code.
- ESCI - We are already using the generic ECSI code from the repository. We
dropped our earlier separate code
- Etherent - we do have some special code in the driver for errata workaround
for some older devices (e.g. MPC5553) and also code for cache management. Since
we have done so much work around networking based on that driver, we did not
want to swap that one
- DSPI - Karl had written a DSPI driver. Once he gets back from vacation and
has some time I would like him to look at the one in the repository and
investigate, whether we can move to that one. Quite frankly many of our demo
projects using eCOS do some really strange things with the DSPI (e.g. implement
serial audio interfaces or MOST MediaLB, ...) therefore I personally have never
used the generic driver, but put my own code into the packages for that
purpose.

Best regards
Stefan
